I have an old iPhone 4s and downloaded Animoog for iPhone to play around with. I’m playing bass into it through my old 1st generation iRig. It works to a degree, but the E and low B strings don’t register. Right now I’m just noodling around at home, but I may want to gig with it at some point. So I’m looking to get a better interface. What’s my best option that won’t break the bank, without serious latency issues? iRig Pro? iRig HD? Sonuus and usb to lightning cable?
